A water heater is a household appliance that every family needs. In recent years, instant electric water heaters have been loved by everyone because of the function of hot water within 3-5 seconds after the water is turned on. The instantaneous electric water heater does not need to be preheated in advance during use, nor does it require an inner tank and a thermal insulation layer in its structural design. Its advantages are small size, light weight, easy installation, space saving, material saving, and service life. long wait.
Water temperature control is very important to the overall comfort of the water heater. The instantaneous water heater has a water temperature control system including an automatic control board, a receiving circuit, a transmitting circuit, a cold water cooling pipe, and a temperature sensor. On the pipe, the temperature sensor and the automatic control board are connected through the receiving line and the sending line, the cold water cooling pipe and the automatic control board are connected through the receiving line and the sending line, and the automatic control board receives the water temperature signal transmitted by the temperature sensor. , to control the working state of the cold water cooling pipe.
The temperature sensor adopts NTC temperature sensor. By adding multiple cold water cooling pipes around the hot water outlet pipe of the water heater heating liner, each cooling pipe is equipped with a temperature sensor, and the multiple cooling pipes are connected to the multiple temperature sensors. on the automatic control panel. When the cold water cooling pipe temperature sensor transmits the water temperature data to the automatic control board, the automatic control board makes control instructions according to the received data to control the work of several cold water cooling pipes: when the water temperature is high, the automatic control board controls the working of the cold water cooling pipe. The number is more; the water temperature is low, the opposite is true.
The instant water heater temperature sensor has a built-in NTC temperature sensor, which can stably control the water temperature, and can adjust the set temperature of the water heater according to the environmental temperature changes, and can determine the corresponding preset water temperature according to the environmental changes to meet the needs of user comfort.
Threaded head NTC temperature sensor, NTC temperature sensor is made by welding a highly sensitive, highly reliable, and highly waterproof NTC thermistor to a wire, and encapsulates it into the required shape with insulating, thermally conductive and waterproof materials, which is convenient for installation and temperature measurement. This NTC temperature sensor is used to detect water temperature, and it is in direct contact with water, with fast response speed, stable performance and good waterproof performance.
